Hey
.Net Framework includes all previous versions. You only need the newest one.
If, for some reason, you dont want 4.7.2, then you can uninstall .net. You do that in program and features, then "add windows features". And unclick the box with .NET and all sub boxes to it.
WARNING, doing this, removes .NET from your system, including security etc. And applications that rely on .net, will not work.
You can then manually install Framework 4.5.2 IF you have the installation file for that version.
I do not recommend this.
May I ask, why you are trying to install 4.5.2?
